    I'm not commercial, so don't have the hours each day most on this forum do.

    Does anyone sharpen blades based upon hours used?

    I dont do it based on hours but I would say if you did it like every couple months it would probably be more than enough if you are just mowing your own yard.

    Every 10 hours or so would be fine.

    Hello All,

    We strongly recommend a range of 8-12 mowing hours, by this time the pointed TIP of the blade, which is the primary cutting tooth becomes rounded or a radius. When this TIP or tooth of the blade is rounded you tear the grass rather than cut it, which leads to yellowed lawns and disease.

    Thank you,

    It depends upon the vegetation being cut and the speed at which you wish to cut that road weed.

    In short, are you working on your tan?


    Do you want to get it done and on to the next thing on the list you should've had done last week?

    I don't play here in North Florida. I cut 7+ acres of the toughest bahia you can imagine.
    I also do it at the fastest speed my Ferris will drag my behind.
    Hit each blade once and get on to the next one.

    It's just this simple. If my butts in the saddle I've got fresh blades under me.

    Do you saddle up your horse to come in second place?

    Most people up north don't know how tough it is to cut these heat tolerant grasses.
    It's like trying to cut leather at 10 mph.

    That's just me, though. I admit that I'm anal about a lot of things anymore.

    The simplest way to find out if your blades need sharpening is to get down there and look at them. If they are slightly rounded then it is time to sharpen them. If just one of them is dull looking then time to sharpen all of them. You can't tell just by the hours. New blades can take a lot longer to dull. You may hit rocks and/or sand. Different types of grass take a toll on blades etc

    I'm probably overkill, but I sharpen every 3rd week or every 5th or 6th cut. KBG in New Jersey
